Answer:
Therefore, equation of the line that passes through (-1,5) and is parallel to the line
is
![y=-2x+3](https://tex.z-dn.net/?f=y%3D-2x%2B3)
Step-by-step explanation:
Given:
.Equation of line
can be written as
...which is in Slope intercept form
To Find:
Equation of line passing through ( -1, 5) and is parallel to the line 2y+4x=-8
Solution:
...........Given
Comparing with,
....general form in slope intercept
Where m =slope
We get
![Slope = m = -2](https://tex.z-dn.net/?f=Slope%20%3D%20m%20%3D%20-2)
We know that parallel lines have Equal slopes.
Therefore the slope of the required line passing through (-1 , 5) will also have the slope = m = -2.
Now the equation of line in slope point form given by
![(y-y_{1})=m(x-x_{1})](https://tex.z-dn.net/?f=%28y-y_%7B1%7D%29%3Dm%28x-x_%7B1%7D%29)
Substituting the points and so we will get the required equation of the line,
![(y-5)=-2(x-(-1))=-2(x+1)\\\\y-5=-2x-2\\y=-2x+3......Equation\ of\ line](https://tex.z-dn.net/?f=%28y-5%29%3D-2%28x-%28-1%29%29%3D-2%28x%2B1%29%5C%5C%5C%5Cy-5%3D-2x-2%5C%5Cy%3D-2x%2B3......Equation%5C%20of%5C%20line)
Therefore, equation of the line that passes through (-1,5) and is parallel to the line
is
![y=-2x+3](https://tex.z-dn.net/?f=y%3D-2x%2B3)
Answer:
180 degrees
Step-by-step explanation:
Answer:
64
Step-by-step explanation:
Answer:
Step-by-step explanation:
<h2>
1) </h2>
scale is 1 inch=9 feet
4 inches*9= 36 feet
10 inches*9=90feet
<em><u>it is 36 feet by 90 feet</u></em>
<h2><em><u>
2)</u></em></h2>
scale is 1 inch=5 feet
4 inches*5=20 feet
<em><u>it is 20 feet</u></em>
<h2>
3)</h2>
scale is 1:12
14 inches*12=168
it is 168
The x value will change to y avlue and vice versa
so x---> y and y---> x
(x,y) --> (y,x)
